Tips on how to Calculate CAGR

Compound annual development price (CAGR) measures the constant development price of an funding over a particular time frame, no matter interim fluctuations. Listed below are 8 vital factors about calculating CAGR:

  • Outline Funding Interval: Begin and finish dates.
  • Calculate Ending Worth: Remaining worth of funding.
  • Calculate Starting Worth: Preliminary worth of funding.
  • Apply Method: (Ending Worth / Starting Worth)^(1 / Variety of Years) – 1.
  • Specific as Proportion: Multiply by 100.
  • Geometric Imply: CAGR is a geometrical imply, not arithmetic imply.
